Full origin of XLSX →Frequently asked questions
What is the difference between XLSX and CSV?
A CSV is a plain list of values separated by commas, one row per line, with no formatting, no formulas and only one sheet. XLSX keeps everything a spreadsheet program can do: several sheets, live formulas, cell colours, charts and number formats. CSV travels between systems more easily; XLSX preserves the actual spreadsheet.
What is the difference between XLS and XLSX?
XLS is the older binary Excel format; XLSX replaced it in 2007 with a zipped, XML-based structure. XLSX files are generally smaller, less fragile and support far more rows — just over a million per sheet, against the 65,536 limit of XLS.
Can I open an XLSX without Excel?
Yes. Google Sheets, LibreOffice Calc, Apple Numbers and various free viewers all read XLSX. Uncommon features such as certain chart types or macros may not carry across intact.
